MRPA Corridor Study

The Chattahoochee River is superseded by the Georgia Metropolitan River Protection Act (MRPA). All construction and development actions, clearance, land disturbance, landscaping, occupancy and use of lands within the Chattahoochee River Corridor shall be undertaken in conformance to the provisions of the MRPA. Protection criteria are established for a 2000 foot corridor from the edge of the Chattahoochee River. This includes a 50 foot natural buffer on both sides of the river; a 150 ft building setback; a 35 foot buffer on tributaries; and controls on floodplain development and the extent of impervious surfaces. The Act specifies that local governments review land-disturbing activities and certify that development follows the guidelines for watershed protection. All proposed development plans within this area shall follow the land vulnerability analysis of the Atlanta Regional Commission document entitled Chattahoochee Corridor Study (July 6, 1972). This GIS data was digitized from Chattahoochee Corridor Sturdy LAND VULNERABILITY Map provided by Atlanta Regional Commission in 2007.
